Question

In the depletion region of an unbiased P-Njunction diode there are

• A. Only electrons
• B. Only holes
• C. Both electrons and holes
• D. Only fixed ions

Answer 1

The correct option is C Both electrons and holes

In an unbiased $\text{p - n}$ junction, there is same amount of the $\text{p -}$side and the $\text{n -}$side. In the depletion region, they produce the same number of both electrons and Holes.
